Precision Axle Bearings?

Cass asked me whether I wanted Precision or Timken bearings on the axle.
Unfortunately he hasn't got back to me, presumably he's busy, so I'm going to ask here.
What's the difference?
I've always used Timken.
Before someone writes that Precision is Green Roller bearings, that is not what he wrote.
Just different brands of tapered roller bearings.

I have ve noticed Timken's seals are just rebranded from others but didn't know if they still made the bearings in house. Precision I am unfamiliar with.

I do know that Timken was sending different types of seals in their boxes. The owner/manager of a local parts store said he stopped carrying them because customers were coming back asking why one seal is different than the others.
